Description of the invention (5) The ribs 2 7 and 2 8 are provided so as to protrude from the facing surface of the cylinder, and the chain sleeve 24 is used as the individual inner definition of the bearing cover group 2-extending from the steam cover 4 To the oil pan for the ribs 27 in the chain box 25 β, in the cylinder group; [on the side, as for the rib portion 27b shown in the figure, are continuously provided so that γ: is different from that on the bearing cover group 2 Ground from cylinder group 1 and bearing cap group 2 bis on the inner surface of the upper 24 on the crankshaft pulley side <# 28, # = dog out, and is provided in the position of the chain sleeve and thus the protruding system is provided so as to be substantial Corresponding square 5: The ribs 28 on the inner surface of the chain sleeve 24 are cut at the opposite side; a portion of the extension portion of the tension bottom plate 18 is cut. In this way, the rib 28 faces the tension bottom plate. One of the front surfaces i8a of 18 has a tiny gap formed between them 'and the rib 28 is carried by the abutment with the distal edges of the ribs W, 27b provided so that the rest of the ribs from the cylinder group The outer surface of the work and shaft ^ cover group 2 protrudes. In this structure, the ribs 27 on the outer surfaces of the cylinder group 1 and the bearing cover group 2 and the ribs 28 on the inner surface of the chain sleeve 24 (a part of which is partially cut) are all Provision is made to protrude toward the side of the tension bottom plate 18 perpendicular to the crank shaft, that is, the front and rear sides 1 8 a, 1 8 b ′ of the tension bottom plate 28 bis at the portion where the tension bottom plate 28 extends, and these The ribs cooperate with each other to define an oil path 26 ° inside the chain box 25. In addition, since the rib 28 faces an end surface of one of the shock support shafts 29 of the tension bottom plate 18, it can be used to prevent the shock support shaft 29 from being displaced. The oil passage 26 communicates with a space above the oil surface in the oil pan 3, and the oil flowing down is directly recovered in the oil pan 3. On the other hand, the space separated by the ribs 2 7, 2 8 and the tension bottom plate 1 8 with respect to the oil path 26, acts as a page 10. 89130020.ptd 470810 V. Description of the invention (6)-Crank Box ventilation path. Bayi? In the present invention, because the tension bottom plate 18 can be formed without the need to improve the tension plate, the risk of the deterioration of the tension bottom plate 18 due to the increase in weight can be eliminated. In addition, as shown in the imaginary line in FIG. 6, The ribs 27 and 28 can be provided so as to protrude from the position where the tension bottom plate 8 is overlapped, and the degree of freedom of position setting can be increased according to the width of the tension bottom plate 18. ^ Motor E is slightly inclined to the left on the side of the eight cylinder head 4 and comes from the cylinder 盍 4. The oil system is constructed so that it flows down to the left as shown in FIG. In addition, the plunger device 17 and the hydraulic control valve 23 for the zipper are provided on the oil path 26 on the engine side, and the oil flowing out of these devices can also be highly efficiently recovered. In the mode of carrying out the aforementioned invention, it has been described that the ribs are placed on the movable tension floor 18 in a manner facing each other, but even if the ribs are provided on a fixed guide floor, it can be formed Separate j similar to the previous one. In addition, in the mode of carrying out the aforementioned invention, in a case where the engine is tilted in the opposite direction, as shown in FIG. 1, the ribs are provided on the guide bottom plate 9 on the right-hand side of the engine to form A separator. 7 and 8 show another mode for carrying out the present invention. In this mode, an extension and extension 2Ob is provided at a part of the assembly of a guide base plate 20 for the fuel pump drive chain, and in this way, one of the bearing cover groups 2 is provided. The rib 27b protrudes, and the extension portion 20b is held between the rib 27b and the distal edge of a rib 28 provided on the facing surfaces of the bearing cover group 2 and a chain sleeve 24, respectively. Even in this configuration, the rib 27b, the rib 28, and the extension portion 20b of the guide bottom plate 20 can still cooperate with each other to form a separator.
